Read a book (or a website or two). I'll save you the trouble, here are the highlights. (https://www.dummies.com/religion/christianity/catholicism/catholicism-and-the-ten-commandments/)
I picked this site because it is specific to Catholicism. Catholics and Protestants interpret the Ten Commandments differently, so I'm giving you the benefit of the doubt there, perhaps you're using the Protestant interpretation in your misguided drivel.
Here's the one that he definitely broke:
"Thou shalt not covet thy neighbor’s wife.”
"The Ninth Commandment forbids the intentional desire and longing for immoral sexuality. To sin in the heart, Jesus says, is to lust after a woman or a man in your heart with the desire and will to have immoral sex with them. Just as human life is a gift from God and needs to be respected, defended, and protected, so, too, is human sexuality. Catholicism regards human sexuality as a divine gift, so it’s considered sacred in the proper context — marriage."
I don't see anything about PROPERTY. Not sure where you're getting that from, but I have a guess (see meme). What I find funny is that in 1976 even the POS Jimmy Carter "confessed" that he had "...lusted after a woman in his heart". Funny how far we've come since then.
So yes, he definitely broke the 9th Commandment. Regarding the 6th Commandment, yeah, it probably happened after two months of dating, but I don't have any proof.
“Thou shalt not commit adultery.”
"The sixth and ninth commandments honor human sexuality. This commandment forbids the actual, physical act of having immoral sexual activity, specifically adultery, which is sex with someone else’s spouse or a spouse cheating on their partner. This commandment also includes fornication, which is sex between unmarried people, prostitution, pornography, homosexual activity, masturbation, group sex, rape, incest, pedophilia, bestiality, and necrophilia."
And again, even if they did wait until after her divorce was final and before they were married, that is still adultery according to the Catholic church ("This commandment also includes fornication, which is sex between unmarried people").
